What About Home Energy Audits?

This is something that most people don’t think of when it comes to making sure that their HVAC equipment is working as well and efficiently as it should be, but they’re absolutely essential for proper maintenance, and can often identify hidden problems that could be costing you big money in your power bill each month.

At MM Comfort Systems, we offer three different levels of home energy audits, from our basic inspection, which is just $95 plus tax, all the way up to our premium package, which sees us applycutting-edgee technology to give you the most detailed and comprehensive view of your home’s HVAC system so you know exactly how well it is (or isn’t) working for you.

For more information about our various home energy audits and what’s included at each level, check out our home energy audit page!

Is It Time To Replace Your Aging System?

If your system is older than 10-15 years, then yes, it’s probably time to start thinking about an upgrade to something new.  The main reason is simply that no matter how well you’ve maintained your aging equipment, at that point, it’s going to start breaking more often.  Add to that the fact that even if your old system was cutting edge when you first bought it, the systems you can get today are vastly more efficient, which means they can save you money each month on your power bill, once installed, and you’ve got a pretty compelling case for replacement.

When you’re ready to do that, be sure to check out our site for the latest deals and promotions.  Often, equipment manufacturers will run seasonal specials on new equipment installations, and of course, we sometimes run deals, specials and promotions ourselves.  These can be combined to save you big money, on top of the monthly savings you’ll realize.

MM Comfort Systems is an authorized Carrier dealer, so we work with some of the best equipment in the industry, including:

  • Gas & Oil furnaces
  • Water heaters
  • Heat pumps
  • Fireplaces

And more.  No matter what your needs are, MM Comfort Systems has you covered!  Check out our online product catalog for a full listing. Not looking for heating services? We also offer cooling services as well.
